A compared result is fed back to the amplifier 4 for the (f) characteristic adjustment and a compensation amount is increased/decreased. Then, the reference signals S1 are sampled from the output of the amplifier 4 for the (f) characteristic adjustment by the amplifier for gain adjustment, compared with a reference level VREF by the comparator 11 and fed back to the gain adjustment amplifier and adjustment is performed so as to turn the difference to '0'.  Thus, the compensation characteristics provided with the flat frequency characteristics from a low band to a high band are obtained.

Filed: 1999-02-03
Abstract: PROBLEM TO BE SOLVED: To continuously measure the characteristics of the living body by moving the position of the tip chip in a way to keep contact with its tissue and detecting the moving amount of the tip chip. SOLUTION: The tip chip 6 is pressed to the viable tissue in a state of being in contact, vibration generated in a signal generator 1 is generated in a vibration exciter 3 and the vibration is applied to the viable tissue. By measuring the vibration stress and vibration acceleration of the tip chip 6 by an impedance head 5, the mechanical impedance of the viable tissue is measured. A static contact load is measured with a load measurement device 4, a depth at the time of pushing in the tip chip 6 is measured with a detector 8 and elasticity is measured. Since the mechanical impedance is continuously measured while pushing the tip chip 6 into the viable tissue, the mechanical impedance at each depth of pushing is measured. Also, by comparing the change of the mechanical impedance, the characteristics such as viscosity of the living body are estimated.

Abstract: PURPOSE:To increase the productivity of magnetic bubble memory elemets with low cost, by providing at least two pieces of specific loops storing specific information in a minor loop. CONSTITUTION:In a minor loop 1, two marker loops 1a and 1b as address marker loops are provided. When two loops 1a and 1b have no deficiency, an address marker 2 is stored in the two loops 1a and 1b or can be stored in the loop 1a. If one of the two loops 1a and 1b is deficient, data 0s are written in all the bits in the loop. After the application of power supply, when the elements are initialized, a BMC checks the content of data of the two loops 1a and 1b, and when data 1 is detected at first, the content is taken as the reference of address, and it is registrated in the register as deficient information by referencing the content of other loops of the same page as the detection of the marker bit. Thus, the productivity of the elements is increased and the cost is decreased.

IPC: G01H1/06
Filed: 1990-02-06
Abstract: PURPOSE:To facilitate part feeding efficiency by displaying oscillating frequencies in digital values, and adjusting the driving frequencies of a vibrator. CONSTITUTION:A spiral track is formed in the inside of a bowl 50. Slant plate springs 47 are arranged at an equal angle space. The bowl 50 is coupled with a base block 44. An electromagnet 46 around which a coil 9 is wound is fixed to the block 44. Thus, an oscillation part feeder 40 which is driven at high frequency is constituted. The inverter part of a driving control circuit 41 is connected to the coil 9. The bowl 50 is driven and controlled at a specified amplitude. The oscillating frequency is displayed on the display part of a control box 42 in a digital value. In this way, a worker accurately reads the change in oscillating frequency of the bowl 50. The generated frequency of the circuit 41 which is associatively moved with a volume 52 is adjusted. Thus the intended amount of feeding of parts is obtained. When the part feeding efficiency is lowered, the cause can be checked so as to determine which is the case; the oscillating frequency, the trouble in the oscillating system or the fluctuation in voltage.
